Product Description
The VI701 S1 is a high-speed Vnet/IP interface module developed by Yokogawa Electric Corporation for the CENTUM VP integrated production control system.
Designed for installation in Human Interface Stations (HIS) or Field Control Stations (FCS), the VI701 S1 provides a deterministic, real-time communication gateway over a 1 Gbps Ethernet-based Vnet/IP plant network. The S1 hardware revision ensures enhanced signal stability and long-term reliability for continuous 24/7 industrial operations.
Unlike general-purpose Ethernet cards, this module is engineered specifically for Vnet/IP, prioritizing time-critical control signals to prevent latency and support high-availability network architectures.

Engineering FAQ
What is the difference between VI701 and VI702?
The VI701 S1 is a standard PCIe-based Vnet/IP card, while the VI702 supports specialized or updated form factors. VI701 remains the standard for rack-mount and tower HIS workstations.
Does this module support network redundancy?
Yes. The VI701 S1 has two onboard ports (Bus 1 and Bus 2), allowing seamless failover within a dual-redundant Vnet/IP architecture.
Is special software required?
Yes. Installation requires the Yokogawa Vnet/IP driver, typically included with the CENTUM VP software package. Proper IP address assignment within the Vnet/IP range is necessary for integration.
